To all 'whom 'it 'may concern:

Be it-known that I, BRNABAS LANGDON, of the city of Troy, in the countyof Rensselaer and State ot' New York, have invented a new and ImprovedGultivator; and I do hereby declare that thei'ollowing isa full andexact description.

The implement here to be described being for thepurposeofhilliug corn,billing and digging or turning potatoes out of the ground, and the;like, and cutting up weeds between the same, aswell as for loosening theground, and being also in its form and proportions and mode of 'beingmanaged somewhat in resemblance of enough to allow of' their beingsubstantially attached thereto either inthe manner shown in the drawingsor by any other'comuion mode of fastening.' The loweredge of thestandard is extended'in a direct line horizontally to any discretionarylength. From the forward termination of this edge, as shown at f, Fig.3,in which the whole of thestandard is separately represented, a plate,dd, is made to projectas a-wing on each side, extending backat an an,

gle'withthe sides of the middle plat-e. of about 4 forty degrees, audhaving the't'orward edge ot each wingon 4alevfel with the lower. edgeofthat plate.' From 'this forward edge the plate of the wingsina'crosswise'direetion'isinclined upward, 4 so as to give to eachaboutthe slant of acemmon plow-sh are.. Thesewi-ugs are cast lwith. theupright. partpi 'th/Standard all as i one' piece,"and for ordinarypurposes they are- 'made to spread from seven to eight inches from themiddle 4plate on each side.A The plate of gsat theline o fitheirjunction 'with each'other'is about six inches wide and about threeadjafhalt' 'i at `its outward' termination.'` i l fvarythem, however,in"each and. all of these i particulars at my option.`

withnuts on the underl side.

From near the poiutoi 'termination ot the upright part of the standard,where it unites with the plate of the wings, as shown in .the drawings,a rib about` half an 'inch wide is raised from the upper surface of eachwin g, extending parallel to the Aforward edge ot'jthe plate to itsoutward extremity. The shoulder thereby formed on each side-of' the rib,in co`ny hection with the surface of the plate, consti-y tutes a seat orbed for the several appendages yet to be described. i in its place at CC, Figs. l and 2}bein g in the t form of its construction fitted to thebed thus provided on 'theforward side of the rib, is

there secured by means of a bolt -through each wing, as at c e in, thefigures last referred to,

This cutter, including both wings, is also cast whole-as one piece,having a section of small cutting width .and of' a chisel form in front,as shown in the same figures, for the purpose of favoring the practicaloperation of the implement; and I give .t0 the forward .edge of theupright part of the standard, as also shown in 'thedrawin gs, a .curveand slant corresponding withthisforin ot' construction of" the cutter.

` A mold-board is also provided, and placed,l when employed, on theupper side of the rib,

with its Vlower edge resting against it, being otherwise litted to theentire Ibed or seat'as thus provided, and it will be perceived that ittis adapted to mold-boards of varicuswidths, as occasion mayrequire.,Onev is vshown in place at B, Fig. 1, and separatelyin Fig. 4, with `avflange from its inner upper corner'for attach' ing itto lthe standard bymeans ot'. a screw-bolt. As these'niold-boards areonly used occasion-,ally `lwhen required, I calla them portable mold-boards.t I usuallyemploy them for hill-'- ing, turningout potatoes, or the like. v

For the purpose of loosening the ground or reducing its surface' to a`tinrr state than it was previouslyin, I provide a'plate to be fixedover each wing4 inthe seats,as already-described for the n1old-boards,assho-wn in their placeat E E, Fig. 2, supplied iwith twoor more upright'cutters',l each extending -up from 'two to three inches from theAplatenertically as respeets'theL '-.plates' of the cuttersthemselves,'hut withtheir forward cutting-edges slanting back at anangie from a perpendiculnrA of fabout thirty-tive A share orcutter,(showm.

degrees, or* so ,us to prevent-the lodgment of weeds or thelike againstthem. Tholbottoln of the upright; cutters extend acrossthe plate tovwhich they belongin directions parallel to the sides offthe upright postot lthe standard.

' The depth ofthe libs uponl the wings ofthe t standard", asabo'vledrscribed, isubout equalto' the thiekness ot' the plutestofbeplaced in' -connection with them' on euch side, in'older to present; 'aneven outside surface'. Y

In the practical application of the above-de-v scribed cult-ivator'. tothe purpose of 'cutting up weeds, hilling corn, or the like,v it; isnecessary to employ a wheel at .the forward'end ofthe.
